This invention relates to that class of 7 safety razors which comprise athin blade clamped between two plates, namely a lower guard plate and anupper cover plate, the cover plate being connected with the guard plateby a detachable resilient locking support.

The known connections of this type have springs which either vibrate sostrongly that they affect the sure guiding and bearing of the cuttingedges of the blade against the skin, or they are separate from thehandle so that the razor is difficult to assemble, disassemble andclean. Other known safety razors have holders which are movablerelatively to the guard plate and depend to a great extend upon theguide being absolutely clean and free from lather and hairs.

The safety razor according to the invention is not open to theseobjections. The resilient support usually forms with the handle a unitedwhole, capable of being disassembled in exceptional cases, and adaptedto carry the cover plate and guard plates so that they are easilyremovable by means of pins and pin holes. The bearing or saddle-shapedconcave part of this support also constitutes the resilient means whichin cooperation with a pin provided on the cover plate enable these partsto be reliably held in proper position for use, merely by a relativedisplacing of the support and plate and aiford the appreciable resilientchanging of the blade which is of great importance for shaving.

A form of construction of the safety razor according tothe invention inwhich the handle is set at an incline to the blade-holding plates inknown manner, is illustrated by way of example in the accompanyingdrawing in which:-

Fig. 1 shows the head end of the safety razor in a part longitudinalsection.

Fig. 2 is a perspective view of the resilient support on the top end ofthe handle.

Fig. 3 shows the guard plate in end view.

Fig. 4 is a front elevation of Fig. 3.

Fig. 5 is a perspective view of the safety razor but with the omissionof the blade from between the plates.

The cover plate I, which is of known curved cross-sectional shape has,as usual, on its under side three spaced pins 2, 3 and 3a. The middlepin 2 is slightly longer than the side pins 3 and 3a and has a thin neck2a with a flange 2b formed on its end and of the same diameter as thebody of the pin 2.

The guard plate 4 has a hole 5 of the same diameter as the pin 2, 2a, 2band two recesses 50, 5b corresponding with the pins 3, 3a. The

guard plate 4 has on its surface adjacent the razor blade 6 a plurality,in the present instance four ribs 1, 1a and in its under surface a flatbottomed recess 4a rounded at its ends, and slightly wider than thewidth of the resilient support 8 hereinafter described.

The resilient support 8 has a concaved upper arm 8a designed to bearagainst the guard plate. The arm 8a may be made symmetrical to the otherarms of the support but in the example illustrated it is non-symmetricalbecause the support, as shown in Figs. 1 and 2,has to support a platesystem which is intended to assume an inclined position relatively tothe axis of the handle. As shown in Fig, 2, the support 8-8d, which isformed from a bent metal, is of chair or saddle-shaped cross section.

The upper arm 80. of the resilient support has a guide slot 80, thelower end of which merges into, for example, a circular widening 8b inthe horizontal arm of the support, whereas its upper end terminatesapproximately in the axis of the handle 9 which is detachably connectedto the horizontal arm of the support by a screw It) or the like butnormally remains connected therewith.

For ensuring the desired position for use of the razor, the pin 2 ofcover plate I together with the blade 6 lying between the under surfaceof the cover plate I and the upper surface of the guard plate 4 is heldbetween thumb and index finger, its flange 21) being thus inserted intothe widening 81), whereupon the neck 20. is slipped in the end of slot80. The concave arm 8a of the resilient support engages in the recessv4a in the guard plate 4 and its ends press against the bottom thereof,whereas its middle portion presses against the upper side of the flange2b, thereby pulling the cover plate I downwards towards the guard plate4 and clamping the blade 6 tightly between the two plates. The rib-likeedge portions of the plate 4 guide the edges of arm 8a of the resilientsupport and bring the plates into the proper position.

Owing to the pin 2 with neck 2a and flange 2b engaging in the long slot80, the parts I, 4 and 6 are held together and the safety razor is easyto manipulate and can be rapidly fitted together and mounted on andremoved from the 7 resilient support. Moreover, any slight differencesin the lengths of the pin 2, 2a and irregularities in the thickness ofthe guard plate 4 are example all three pins 2, 3 and 3a instead of onlythe pin 2, for which purpose the pins 3, 30. would evidently have to beconstructed like the pin 2.

The longitudinal edges of the guard plate 4 are provided in known mannerwith teeth or projections 4e and have recesses or gaps 4c for thepassage of the lather into the space between the ribs 1, la of the guardplate 4 and the cover plate I. g

The parts I, 4 and 9 in the form of construction described andillustrated can be made of artificial resin or the like by moulding andpressing, so that they are very light and cheap to manufacture. Only theparts 2a, 2b,'8 and ID are preferably made of metal.

We claim:--

1. A safety razor, comprising in combination a cover plate provided witha centre pin and two side pins on its under side, a guard plate havingapertures registering with and adapted to accommodate said pins, a razorblade with three holes adapted to be clamped between said plates, a neckformed on said centre pin, a flange formed on the end of said neck, aresilient support, a concave top arm of said support adapted to hear atits two ends against the under side of said guard plate and having aslot adapted to accommodate said centre pin, the flange at the end ofsaid centre pin bearing against the side of said resilient arm, and ahandle carrying said support and adapted to shift the same relatively tosaid plates to clamp said blade therebetween.

2. A safety razor as specified in claim 1, in which the handle, thecover plate, the guard plate with the exception of the centre pin aremade of a non-metallic, plastic thermo-setting material, such asartificial resin.

3. A safety razor as specified in claim 1, in which the support consistsof a metal strip, and the upper arm of said support is bent in chairorsaddle-shape and in which the slot in this concave upper arm merges intoa circular hole at its lower end of a diameter adapted to allow thepassage of the flange or the centre pin and terminates at its upper endapproximately in the axis of the handle.

4. A safety razor as specified in claim 1, in which the centre pin has aneck of a diameter slightly smaller than the Width of the slot in theresilient arm of the support and carries on its lower end the flange ofthe same diameter as the pin proper.

5. A safety razor as specified in claim 1, in

which the guard plate has in its under side a U-shaped channel slightlywider than the concave resilient arm of the support and adapted to guidesaid support. V,

6. A safety razor as specified in claim 1, in which the resilientsupport is detachably connected with the handle.
